[PATCH] intel-iommu: Make "Unknown DMAR structure" message more informative

[Roland Dreier]

We might as well print the type of the DMAR structure we don't know how
to handle when skipping it.  Then someone getting this message has a
chance of telling whether the structure is just bogus, or if there
really is something valid that the kernel doesn't know how to handle.
